In recent years, there has been increased interest in the use of wearable devices as next-generation information terminal devices, healthcare devices, and medical devices that are thin, light, and adaptable to various shapes, and that do not break when dropped. Several reports on wearable electronics have already been published. However, there are still many issues that need to be solved to industrialize these wearable electronics. We believe that printed electronics technology will help wearable devices to be effectively manufactured and be diffused into everyday life. However, conventional silicon devices are also necessary for producing highly usable wearable devices. Therefore, there is a need for reasonably hybridizing printed technology to conventional silicon technology to produce excellent wearable devices.
